Application filed. March 16, 1917, Serial-No. 155,556. Renewed October 20, 1519. Seria1No.382,128,

To all whom it maycon'cem:

Be it known that I, RALEIGH J. ADAMS, a citizen of the United States, resident of Los Angeles, in the county of Los Angeles and State of California, have made a certain new, and useful Invention in Steam-Boilers; and-I declare the following to be a full,

clear, and exact description" of the same,.

such as will enable othersskilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of this specification.

Theifigure of the drawing is a verticalsection of the invention.

The invention has relation to steam boilers or generators of the inclined water tube 7 type, having for its object to improve the circulation of water therein, and to reduce the formation of scale; lThe invention consists in the novel construction and combinations of parts as hereinafter set forth.

In the accompan ing drawings illustrating the invention, t e numeral 2 designates the incaser'nent, 3, the furnace a, the grate d 6 the outlet character.

' 7 and 8 designate bafiies of suitable refractory material.

Supported from the horizontal beams 9 are saddles, 10, carryin a forward transverse steam and water d r'um 11, and a rear transverse waterdrum 12, the latter bearing thereupon a saddle 13 supportin in turn a steam drum 14, located immediate y above the water drum. A lower mud drum 15 is located below the superposed water and steam drums in rear of the plant or furnace.

The mud drum is connected with the steam and water drum by a bank of tubes 16 inclined at an angle of approximately forty-five degrees; the. steam and water' drum is connected with-the water drum by a bank of tubes 17, a proximately horizontal, but having a slig t downward inclination, and the water drum is connected with the mud drum by a bank of approximately vertical or upright tubes 18.

The steam and water drum is connected withthe steam drum by a line of approximately horizontal tubes 19.

steam passing through the bank of tubes 17 to the water drum and thence to the 'mud drum, which is provided with the usual blow off 20.

A lineof approximately vertical equalizer tubes 21 is usually provided betweeruthe steam drum and the mud drum. 7 v The circulation of water is upward through the inclinedbank of tubes- 16' to the steam and water drum, thence ,rearwardly through the. horizontal-tubes 17 to the water drum, and downwardly therefrom.

to the mud drum, steam from the steam and water drum passing over through the upper line of tubes 19 to the steam drum, the latter being separate and apart from the water circulatory system, and bein connected with the steam an water drum and at the other side with the mud drum.

The water intake 22 .is usually located in the steam and water drum, the steam outlet 23 being. from the steam drum-.' The mud drum is hung from-the banks/of tubes and all parts of the boiler are free to expand and contract without interference.

The steamis disengaged from the water in the forward water and steam drum 11, said drum being located at the hottest part of the boiler, at the upper termination of the forwardly and upwardly inclined water at one side tubes, or at the upper end of its first pass over the fire. These water tubes 16 being inclined at' about forty-five degrees, may

thereby be made longer than if inclined at a lower angle, the distance from one end to the other, horizontally, being constant, or

the size and type of boiler being the same.

The equalizer tubes 21 enable me to equalize the water inside the boiler setting, dispensing with outside equalizers. 1

. This boiler is designed to improve the water circulation, to eliminate pockets of water in the circulating system, and will drain completely of waterwlien desired. I claim In a steam boiler, a forward transverse steam and water .drum, a rear transverse 'cylindrical steam drum, a rear transverse cylindrical water drum directly below and spaced apart from said steam drum, sub-' stantially horizontal self-draining tubes connecting said steam and water drum with side upright equalizer tubular connections said water drum, a rear transverse mud with the mud drum. I 10 drpm, upright tubes connecting said water In testimony whereof I afiix my signature drum with said mud drum, inclined tubes in presence of two witnesses.

connecting said 'mud drum with said steam RALEIGH J. ADAMS. and water drum, said steam drum havingat Witnesses: one side thereof tubular connections with A. M. FOWLER,

the steam and water drum and at its other C. O. MERsHoN.
